Sydney: A dingo dragged a sleeping toddler from a camper van on a popular Australian holiday island late on Thursday, but his father awoke and pulled his 14-month-old son from the jaws of the animal. The parents woke up to the baby screaming, chased after him, and had to fight the dingoes off to take the 14-month-old boy away. The boy suffered head and neck injuries in the attack on Fraser Island off the northeast coast and was taken to hospital. In 1980, baby Azaria Chamberlain disappeared from a tent in a camping ground in Australia's outback, with her mother claiming she was taken by a dingo. The baby's body was never found, and Azaria's mother was jailed for three years over her daughter's death. It was not until 2012 that a court ruled that a dingo had killed Azaria. Dingoes, introduced to Australia about 4,000 years ago, are a protected species on Fraser Island and are a popular attraction for camping tourists. They are also protected in Queensland's national parks, World Heritage areas, Aboriginal reserves, and the Australian Capital Territory. Elsewhere, they are declared a pest species.

Sydney: A dingo dragged a sleeping toddler from a camper van on a popular Australian holiday island late on Thursday, but his father awoke and pulled his 14-month-old son from the jaws of the animal. The parents woke up to the baby screaming, chased after him, and had to fight the dingoes off to take the 14-month-old boy away. The boy suffered head and neck injuries in the attack on Fraser Island off the northeast coast and was taken to hospital. In 1980, baby Azaria Chamberlain disappeared from a tent in a camping ground in Australia's outback, with her mother claiming she was taken by a dingo. The baby's body was never found, and Azaria's mother was jailed for three years over her daughter's death. It was not until 2012 that a court ruled that a dingo had killed Azaria.

Dear Ann Landers, I'd like to respond to the letter from the woman whose son "Jeremy" was forced by his father to play football. I am an athlete. I played high school and college ball and spent six years as part of 'George Halas' infamous "Taxi Squad" in the early 1960s. When I retired, I spent many hours coaching pee-wee football for boys ages 10 to 12. Ann, watching those kids get hit and hit hard—and seeing the other coaches and parents pushing their children to get up and take it over and over again—really turned me off. Children that age are still developing physically. Hard hits can do permanent damage that may not show up until later. I know; I have knees that ache and buckle, back pain like you wouldn't believe, and I have had surgery on my spine. All of this from being hit by guys while playing a game. In grade school-level football, children who weigh 40 kilograms are sometimes pitted against others who weigh 54 kgs. These kids are poorly coached about protecting themselves, and I can tell you, the ones who really don't want to play are the most vulnerable. I speak from experience. Ex-Football Player The letter to Ann Landers comes from______.

1. an experienced physical trainer 2. Jeremy's mother 3. a former football player 4. a novice football coach 5. a young football player

What is it about loud rock music that makes your ears ring after several hours at a concert or club? Does loud classical music have the same effect? Ringing in the ears is called tinnitus. In the circumstances described above, it can often be accompanied by a temporary loss of hearing known as (line 5) temporary threshold shift and indicates damage to the nerves of the inner ear caused by excessive noise exposure. The criterion is not the type of music listened to but the sound energy involved. Rock music, being prone to electric amplification, can generate high noise levels. This tends not to be the case with classical music. (line 10) Repeated exposure to high noise levels can lead to permanent and irreversible hearing damage, and because of this, noise in the workplace is subject to legislation, the maximum permitted exposure level being 90 dBA over an eight-hour shift. Damage of this nature tends to affect hearing mainly at a frequency of (line 15) about 4 kilohertz and presents a characteristic profile on an audiogram. This loss is insidious and may not be noticeable to the sufferer until natural hearing loss through aging begins to occur. At this point, hearing function may start to drop off sharply, and it is, unfortunately, far too late to do anything about it. (line 20) It is best not to expose one's hearing to very high noise levels, but if it does occur, it is important to allow full recovery 16 hours before re-exposure to the sound. You may wonder if rock musicians suffer from this form of deafness; they do. Ring (line 1) means______.

1. Sound familiar 2. Make a call 3. Sound like a bell 4. Become deaf 5. Hear an annoying sound

5. Hear an annoying sound
